Start building your app for free, then pay as you go to production.
Developer on the platform is a user who has an access to platform tools: scenarios, API-builder, database configuring, etc. You can invite new developers from your team and work with them together. Team of developers includes the app owner.
Once per day the quantity of app developers is counted. The final invoice takes the max quantity of developers happened during the period.
As your scenarios run and process data, they consume "processing operations". Different scenarios and different steps create different load on the platform. You can monitor the processing operations on the dashboard.
There is no direct limit. App Users on the platform are just regular objects in data base. You can create as many as you wish. Of course, their usage of your app affects the resource consumption.
There are two options. First. If you hit the limits having turned on the on-demand consumption, then the over limit load will be counted and included into invoice according current plan. Second. If you hit the limits having turned off the on-demand consumption, your app will be paused up to the next month.
You can do it in app's settings page. You can even cancel the paid plan and downgrade to Free one.
